Texture-controlled anisotropic strength and ductility in hot-rolled Mg–2Zn–0.1Ca alloy

This study systematically examines the influence of texture on the mechanical behavior of a hot-rolled Mg–2Zn–0.1Ca alloy. When subjected to tensile loading along the rolling direction (RD), the alloy exhibits superior strength and ductility compared with loading along the transverse direction (TD). Slip-trace analysis reveals that deformation mode in the TD specimens is predominantly governed by basal slip, whereas the RD specimens show a pronounced activation of non-basal slip systems. A modified Hall–Petch relationship, incorporating the combined effects of texture and grain size, suggests that the synergistic contribution of finer grains and stronger textures is closely associated with strength enhancement. Furthermore, the increased work-hardening capacity and improved deformation compatibility promote a more homogeneous strain distribution, thereby delaying intergranular crack initiation and ultimately leading to enhanced ductility.
